ATENT mes DUST AND AIR GUARD FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 727,936, dated May 12, 1903.

Application filed December 31, 1902. Serial No. 137,260. (No model.)

To ail whom it may concern:

Be it known that L'JAMES T. GULESER, a

citizen of the United States of America, and a resident of Ludlow, in the county of Kenton and State of Kentucky, have invented certain new and useful Improve men ts in Dust and Air Guards for Windows, of which the following is a specification.

- This invention relates 'to certain improve ments in weather-strips or dust and draft guards for use more particularly in connection with car-windows of the sliding kind; and the object thereof is to provide a construction of this character of a simple and inexpensive nature and one that is strong, compact, and durable which may be conveniently and effectively made and used for excluding therethrough dust, undesirable weather, and smoke from within the cars.

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved weather-strip, whereby certain important advantages are attained and the device is made simpler and is less exposed to the deleterious effects of the atmosphere and tampering with and is otherwise better adapted and made more substantial and convenient for use than various other forms of weatherstrips and dust-guards heretofore employed, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings, which serve to illustrate the invention, Figure 1 is a perspective view showing the window partly raised. Fig. 2 is a broken sectional elevation taken through the upper part of the window and casing in the plane indicated by theline a: a: in Fig. 1, but with the sash shown closed, and especially bringing to view the construction of dust-guard for the upper rail of said sash. Fig. 3 is a detail perspective view of the inner face of one of the stops or side strips.

forming part of the dust-guard construction. Fig. 4 is a perspective view of one of the up per corners of the sash, showing the inner face thereof, and thus bringing more clearly to view one of the elements of the horizontal dust-guard on the upper rail. Fig. 5 is a detail elevation of one of my stops.

1 indicates the sill, 2 2 the outer opposite side stiles, the sill guard-strip, 4 4 the back jamb-bars abutting the shouldered faces 2 of the stiles 2, and 5 5 the side guard-strips or Istops suitably secured to said jamb-bars, all

these parts comprising the window-casing, except the complete lintel thereof, whichlatter is not shown, it being considered non-essential herein to do so.

6 represents a tapered rabbet,'decreasing in its depth from top to bottom, made along the inner edge of the rear face of each of the stops or guard-strips 5 5, as best seen in Figs.

1, 3, and 5. The stops or guard-strips 5 5 are spaced awayfrom the stiles 2 2, as usual, to provide vertical guideways for the sliding sash.

7 indicates a horizontal bar'or outer lintel, supported at its opposite ends on the stiles 2 2-, and 8 an upwardly-beveled guard-strip secured along the lower edge of the inner face of said lintel or bar 7, its base or thickest portion being of a width corresponding to the depth of the shoulders 2 on the strips 2 2 and bringing said base flush with the guideways.

The sash is made up of the stiles 9 9, upper rail 10, lower rail 11, and glass 12.

13 13 indicate vertical plates or strips secured by screws or other convenient means to the stiles 9 9, with intervening strips of thin rubber cloth or like fabric or elastic material, the latterv being foldedor bent into tapering loops 14: 14, decreasingin widthfrom top'to bottom and projecting forwardly beyond the inner edges of the sash-stiles 9 ".9, as best seen in Fig.1. The taper and extent of projection of the elastic loops 14 14. conform or correspond to the taper'and depth of the rabbets 6 6 along the guard-strips 5 5, so that when the sash is closed the loops will fit snugly within the rabbets, the latter forming compact pockets for the loops and resisting the entrance of dust, air, or the Weather elastic loops within the stops or guards 5 5, especially when they are made of rubber cloth, which is subject to short life when exposed to the weather, insures their protection against quick decomposition, increases their period of usefulness as against rubber strips in common open use on the jambs, and the distance of sliding frictional contact is not great within said pockets to cause the rubber loops to wear out or prolong the lifting strain or resistance on the sash when being raised. These loops may be readily replaced by the provision of said detachably-secured plates 13.

15 indicates a horizontal loop of rubber cloth or strip detachably secured, by means of a plate 16, along the upper rail of the sash from side to side, as best seen in the broken perspective, Fig. 4. This loop is composed of a folded or bent sheet similar to the loops 14: 14, but is of constant instead of tapered projecting width below its securing-plate 16, and when the sash is closed it bears in firm contact or engagement with the beveled face of the guard-strips 8 along the lower edge of the bar or lintel 7, whereby the dust, air, and weather are effectually excluded along the top of the sash. The sill-guard 3 fits snug against the inner face of the lower rail of the sash, as customary, and excludes the dust and weather at that point.

The device constructed as above described is of an extremely simple and inexpensive nature and is especially well adapted for use, since it is durable and not exposed to the deleterious conditions of the ordinary rubber or felt edged weather-strips, which bear in frictional wearing contact at all times against the sash, are easily subject to being tampered with, becoming in use readily worn and useless, and besides the paint,varnish,or the like on the sash-stiles is rough and sticky at times and the rubber or felt frequently torn from place thereby.

My device is readily repaired and replaced and not subject to injury and undue wear to in any wise deter its object in excluding dust, air, and the elements from within the car through the windows.

In Fig. 5 I have shown the stop or side guide 5 detached and how it is made, so as to extend upward beyond the sash-opening for the purpose of providing a continous guideway for said sash above said opening. The upper portion 6 of the rabbet, beginning about mid-length of said stop 5, is of the same depth as the deepest upper part of the lower tapered portion 6 of said stop 5 and remains constant in this extended upper part of the stop, thus allowing sufficient width and thickness in the body of the stop for the proper accommodation of the securing nails or screws.

It is obvious from the above description that my improvements are adapted to other windows than those for cars herein shown and without material difference in application or departing from the principles and spirit of my invention, and I do not, therefore, wish to be understood as limiting my self to the sole use shown and described herein.

Having thus described my invention,what I claim is l. Inadeviceofthecharacterdescribed,the combination of a window-sash having forwardly-projecting, tapered elastic weather strips or guards along its opposite stiles, a window-casing having guideways for said sash and stops or guard-strips having constructed along their inner rear edges tapered rabbets corresponding to said tapered weather-strips and adapted to incase or pocket the latter.

2. Inadeviceofthc characterdescribed,the combination of a window-sash,a weather-strip 15 projecting in expanded form from its upper rail, a window-casing, and a beveled strip or guard 8 along the inner face of the outer lintel or bar 7 of the casing, said projecting expanded strip on the sash closely engaging the beveled strip on the lintel to exclude air, dust and the like at the top of the window, substantially as herein set forth.

Signed at Cincinnati, Ohio, this 19th day of December, 1902.

JAMES T. GULESER.
